Feyenoord will hopefully be a good loan for him. Good club, in a league where he should get plenty of opportunities and could easily play himself into a starting role very quickly. Open league in general. If he can do well there, he could and should be competing for the match day squad next season.
Foreign loans can be necessary but always make me nervous, because if he flops because of non-footballing reasons - culture shock, isolation, language barrier etc - or reason beyond his control - managerial changes, tactical shifts, new signings etc - then it can really set a player back and be a lost year; when he could be here learning from an all time great.
That said, getting a season of regular minutes is the natural progression for him. He’s not yet proved himself week in, week out over a season; so this should be interesting.
Fingers crossed.
